Serial No. 330,791.

The spacing member 1 is in the form of a comparatively narrow strip of wrought metal, preferably straight from end to end and of uniform cross-section. At intervals along the length thereof pairs of notches 1 extend inwardly from one edge thereof about half the width of the strip, and between these pairs of notches recesses 5 extend inwardly from the opposite edge of the strip.

The arms 2 are struck out from opposite edges of the strip 1 and on opposite sides of the pairs of notches 4 and recesses 5.

The supporting members 3 are herein shown in the form of inverted U-shaped chairs comprising depending legs 6 connected at their upper ends by a transversely disposed part 7. Notches 8 extend inwardly from the edges of the legs 6 directly below the transverse part 7 The depth of these notches is about half the width of the mem her. A lug 9 is struck out from the transversely disposed part 7 which, as will more fully hereinafter appear, coacts with the recess 5 for securing the members 3 in their assembled positions on the spacing strip 1.

The spacing strip 1 and supporting members 3 as thus formed are assembled by passing the notches 8 in the legs 6 of the supporting members 3 over the strip 1 to embrace that portion of the strip beyond the notches 41-, while at the same time the notches 4 receive and embrace the legs 6 beyond the notches 8 as is clearly shown in Figs. 1 and 5. Thus assembled, the lug 9 is bent down into the recess 5 and around the edge 10 of the strip 1. Thereupon the supporting members 3 are locked in place.

When all of the supporting members 3 have been properly placed upon the strip 1 and secured thereto, the device is ready for use. When used the device is placed upon the falsework upon which the concrete is to be poured and the bars 11 are placed upon the transverse part 7 of the supporting members 3, and the arms 2 are then bent around the bar 11 in opposite directions as indicated in Fig. 1.

In the 'modification shown in Figs. 5 and 6, thesupporting members 3 are secured in place upon the strip 1-by causing a suitable punch to depress a part of the superimposed portions 7 of the supporting members and the strip 1 so as to form interfitting offset portions 12 and 13 respectively, as more clearly indicated in Fig. 6.

As will be obvious, other modifications may be made and those shown may be further modified or altered or have details omitted without departing from the spirit of this invention as defined by the following claims.

I claim:

1. In a device of the class described, the combination of a spacing member and a separately formed supporting member, each of said members having a slot extending inwardly from one edge, the length of the slots in the two members being substantially equal to the width of one of saidmembers, said members being assembled with the slot in one member extending beyond the slot in the other and each slot embracing a part of the other member which is alined with the slot therein, whereby said supporting member is positioned so as to support said spacing member above the falsework.
